Hi! I've had my betta, Saturn, for about 9 or 10 months now, and he's been doing very well. He's in a 5 gallon hexagon tank with an otocinclus. Last Wednesday (7/14) everything was fine. He swam up to the front of the tank when I fed him and ate his food (betta pellets) like normal. Thursday I noticed he was towards the bottom of his tank around 8 pm I then realized he had been doing this seemingly more often (that I had noticed). Previously I just assumed he was sleeping. Anyway Thursday I decided to take a better look at him and noticed his body was wavy. I don't mean bent over like swim bladder but wavy (you can notice it better when looking straight down on him). I looked things up online which of course said he will most likely die. I then proceeded to vacuum gravel the tank and removed about 1/4 to 1/3 of the water and replaced it. I did a test strip of nitrates, nitrites, etc and everything was fine. The next day (Friday) I did another water change probably more like 1/4 this time and scraped 3 of the 6 sides of algae (and I did another test strip - the nitrates were maybe mildly high). I also added either 1/4 or 1/2 tsp of aquarium salt. During all of my water changes I also add a squirt or two (I know very scientific) of Tetra brand Safestart to keep the good bacteria in there. I'm honestly surprised he didn't die Saturday while I was at work. I changed the filter cartridge Sunday (it had gotten nasty after the water changes and stirring up things). His body doesn't seem to be wavy anymore that I can tell. I did some minor research and found that I should try Maracyn (a fritz mardel product). I went looking for it today (Monday 7/19) after work. Meijer didn't have it and neither did the local pet store. However, I picked up BettaFix. I got home from work and he's still alive. I dropped in 1 and 1/2 tsps of BettaFix. It says 1/2 tsp per US gallon of water. I know I underdosed it. Also today I notice his fins are more raggidy. He still moves occasionally, I'll notice him in different places every so often. Saturn is also at a 50-60 degree angle (nose down) the last few days. He also is slightly uncoordinated when he swims. Now I look at him again, he moved to a different spot and is almost 90 degrees. Is there anything else I should try? Should I add more BettaFix to the appropriate dosage? Can I really dose the aquarium everyday like it says on the back of the bottle? Should I dose it everyday? Any other suggestions would be much appreciated so I can try and save him. Or at least I can say I tried.
